Exercise Capacity of a Breast Cancer Survivor: A Case Study

KLIKA, RIGGS J.; CALLAHAN, KATHLEEN E.; GOLIK, KATHARINA S.

Abstract

Purpose: The processes by which we assess, create an individualized exercise program, and monitor training of a breast cancer survivor who was participating in a fitness plan during and after surgery, chemotherapy, and radiation treatments were examined over a 391-d period.

Results: Over 391 calendar days, the client exercised 343 days (88%) and completed 424 exercise sessions. The client's body composition (15.1%) and body weight (41.4 kg) remained stable for the entire period. There was a significant decrease in V˙O2max (−7.8%) before and after treatment (56.4 to 52.0 mL·kg−1·min−1, respectively). During the treatment phase (6.8 months), the client averaged 1.19 exercise sessions per day, with an average duration of 48.1 ± 25.2 min at approximately 57% of V˙O2max (~32 mL·kg−1·min−1). Posttreatment (~6.2 months), the client averaged 1.32 exercise sessions per day, with an average duration of 69.3 ± 38.5 min at approximately 59.6% V˙O2max (~31.2 mL·kg−1·min−1). Pre- and posttreatment exercise durations were significantly different (P < 0.01).

Conclusions: A cancer survivor who engaged in a medically supervised and proactive fitness plan starting from the day of diagnosis maintained a realistic level of physiologic function during and after cancer treatment.
